DETAILED DESCRIPTION

Reference will now be made in detail to representative embodimentsillustrated in the accompanying drawings. It should be understood thatthe following descriptions are not intended to limit the embodiments toone preferred embodiment. To the contrary, it is intended to coveralternatives, modifications, and equivalents as can be included withinthe spirit and scope of the described embodiments as defined by theappended claims.

In the following detailed description, references are made to theaccompanying drawings, which form a part of the description and in whichare shown, by way of illustration, specific embodiments in accordancewith the described embodiments. Although these embodiments are describedin sufficient detail to enable one skilled in the art to practice thedescribed embodiments, it is understood that these examples are notlimiting such that other embodiments may be used, and changes may bemade without departing from the spirit and scope of the describedembodiments.

The following disclosure relates to electronic devices. Electronicdevices described herein may include mobile wireless communicationdevices (such as smart phones) and tablet computing devices, asnon-limiting examples. An electronic device described herein may includemultiple audio speakers distributed throughout the electronic device.Further, some audio speakers produce low-frequency sound, while otheraudio speakers produce high-frequency sound. As a result, the electronicdevice may provide a dynamic range of sound. Moreover, some audiospeakers, when in use, may acoustically drive the enclosure, or housing,of the electronic device, thereby resonating the enclosure.

The electronic device may further include several microphonesdistributed throughout the electronic device. Some microphones may bepositioned against a sidewall of the enclosure or another wall of theenclosure. Further, some microphones may be positioned on othercomponents. For example, some microphones are positioned on a bracketused to carry a vision system, while other microphones are coupled witha display assembly of the electronic device. Regarding the visionsystem, the electronic device may use the vision system to providefacial recognition and user authentication. This may, in some instances,eliminate the need for “home button” with a fingerprint sensor, or someinput mechanism positioned on the front of the electronic device in anopening of a transparent cover of the electronic device. Accordingly, adedicated opening for a button in the transparent cover can beeliminated.

The display assembly of the electronic device may include a touch inputlayer that used capacitive touch technology and alters an electrostaticfield in a location corresponding to a user touch input. However, thetouch input layer may alter its electrostatic field through interactionwith a digital stylus. In this regard, the electronic device may includean inductive charging unit designed to provide an electrical current tothe digital stylus in order to charge a battery of the digital stylus.The battery may store energy as a result of receiving electricalcurrent, and subsequently supply the energy to components of the digitalstylus, such as a processor circuit, a capacitive component, and a radiocircuit.

These and other embodiments are discussed below with reference to FIGS.1-16. However, those skilled in the art will readily appreciate that thedetailed description given herein with respect to these Figures is forexplanatory purposes only and should not be construed as limiting.

FIG. 1 illustrates an isometric front view of an embodiment of anelectronic device 100, in accordance with some described embodiments.The electronic device 100 may be referred to as a portable electronicdevice. For example, in some embodiments, the electronic device 100 is alaptop computing device. In other embodiments, the electronic device 100is a mobile wireless communication device, such as a smartphone. In theembodiment shown in FIG. 1, the electronic device 100 is a tabletcomputing device designed for user interaction and wirelesscommunication.

The electronic device 100 may include an enclosure 102, or housing,designed to provide an internal volume (not labeled) to store severalcomponents, including (as non-limiting examples) circuit boards,processor circuits, memory circuits, battery (or batteries), audiomodules (such as speakers), microphones, cameras, light emitters andreceivers, and flexible circuitry that electrically connect at leastsome of the aforementioned components to each other. The enclosure 102may include a back wall and multiple sidewalls that extend from, andcombine with, the back wall define the internal volume. The enclosure102 may include a rigid material, including a metal (such as aluminum oran alloy that includes aluminum), ceramic, or hardened plastic, asnon-limiting examples.

The electronic device 100 may further include a display assembly 104(shown as a dotted line). Although not shown, the display assembly 104may include multiple layers, including a display layer designed toprovide visual information. The display assembly 104 may further includea touch input layer designed to receive a touch input, and provide alocation of the touch input. The touch input layer may includecapacitive touch technology used to form an electrostatic field and usechanges in the electrostatic field to locate the touch input. Theelectronic device 100 may further include a transparent cover 106positioned over the display assembly 104 and coupled with the enclosure102. The transparent cover 106 may provide a protective cover to thedisplay assembly 104 as well as the aforementioned components stored inthe internal volume. The transparent cover 106 may include a see-throughmaterial, such as glass, plastic, sapphire or the like. The electronicdevice 100 may further include a border 108 that extends around aperimeter of the transparent cover 106 and covers edges of the displayassembly 104. The border 108 may provide an opaque barrier that hides orobscures electrical connections between the display assembly 104 andother components (not shown in FIG. 1). The border 108 may be applied toan internal surface of the transparent cover 106, and accordingly, theborder 108 faces the internal volume. However, in some instances (notshown), the border 108 may be applied to an external surface. Also, theborder 108 may include a uniform dimension along the X-axis as well asthe Y-axis. In this manner, the border 108 may appear uniform along atwo-dimensional plane, thereby providing the electronic device 100 withan aesthetic and consistent finish.

While the border 108 is opaque, or at least substantially opaque, someportions of the border 108 can be removed to form an opening (oropenings). Further, the opening(s) in the border 108 can be filled witha material that provides a light transmission (or translucent) quality,while also matching, or at least substantially matching, the appearance(in terms of color and/or reflectivity) of the border 108. For example,the border 108 may include an opening with a material 198 that fills theopening. The material 198 may include an ink material (as a non-limitingexample) that includes an appearance that matches that of the border108. For example, if the border 108 appears black, the material 198 mayalso appear black while still allowing light passage. In this manner,the electronic device 100 may include a vision system for userauthentication, as well as light sensors that detect an amount of lightincident on the electronic device 100. These features will be shownbelow.

When the enclosure 102 is formed from a metal, some parts of theenclosure 102 may undergo a machining operation to remove the metal, anda non-metal may fill the void in the enclosure 102 left from themachining operation. For example, the enclosure 102 may include asidewall 114 a having an opening, or window, that opens into theinternal volume of the electronic device 100, and a non-metal material116 a that fills the opening. The non-metal material 116 a may includeplastic, resin, and/or adhesives. In this manner, the electronic device100 may include components, such as an inductive charging unit andantennae (not shown in FIG. 1), positioned in the internal volume alongthe non-metal material 116 a. The non-metal material 116 a providesminimal, if any, blockage of radio frequency (“RF”) communication to andfrom the antennae. Accordingly, the non-metal material 116 a may bereferred to as a radio frequency window. Further, the non-metal material116 a provides minimal, if any, blockage of induced electrical currentfrom the inductive charging unit. As a result, the inductive chargingunit can be used to charge an object or an accessory, such as a digitalstylus, that is used to provide a touch input to the display assembly104. These features will be shown below.

The enclosure 102 may further include through holes, or openings, thatlead to the internal volume. For example, the sidewall 114 b may includethrough holes 118 a and through holes 118 b. The through holes 118 a andthe through holes 118 b may be used to allow acoustical energy generatedby audio modules (not shown in FIG. 1) to exit the electronic device100. Also, at least some of the through holes 118 a and the throughholes 118 b may be used to receive acoustical energy, thereby allowing amicrophone(s) (not shown in FIG. 1) in the electronic device 100 toprocess the acoustical energy. Although a discrete number of throughholes are shown in the sidewall 114 b, the number of through holes mayvary. The electronic device 100 may include a connector 120 located in athrough hole of the sidewall 114 b. The connector 120 may electricallycouple with a central processing unit (not shown in FIG. 1) on a circuitboard in the internal volume, as well as a battery (or batteries, notshown) in the internal volume. In this manner, the electronic device 100may receive and transmit data for the central processing unit, and mayalso receive electrical energy use to charge and re-charge the battery(or batteries). The connector 120 may include a Universal Serial Bus(“USB”) connector, including a connector with USB-C protocol. However,the connector 120 may take the form of other standardized connectors.

Also, the electronic device 100 may include an input mechanism 122 alocated on the sidewall 114 a. In some embodiments, the input mechanism122 a is a switch or a button mechanically coupled to an internalswitch. The input mechanism 122 a may be designed for actuation (such asa depression or lateral movement) to generate a command to alter thedisplay assembly 104 or provide some other function, such as controllingthe volume of the audio modules (not shown in FIG. 1). Although theinput mechanism 122 a is located on the sidewall 114 a, other locations(both on the sidewall 114 a and other sidewalls) are possible.

FIG. 2 illustrates an isometric back view of the electronic device 100shown in FIG. 1, showing additional features of the electronic device100. The enclosure 102 may include a wall 124, also referred to as abottom wall or back wall, with several openings to allow for additionalfeatures. For example, the wall 124 may include an opening filled with anon-metal material 116 b. The non-metal material 116 b may includeplastic, resin, and/or adhesives, as non-limiting examples. In thismanner, the wall 124 may permit radio frequency into and out of theenclosure 102 by way of the non-metal material 116 b. The wall 124 mayfurther include openings for a camera assembly 126, a flash module 127,and a microphone (not labeled).

The enclosure 102 may further include a sidewall 114 c that includes anopening 118 d for a microphone (shown later). The sidewall 114 c mayfurther include an input mechanism 122 b and an input mechanism 122 c,both of which may include any feature previously described for the inputmechanism 122 a (shown in FIG. 1). Also, the enclosure 102 may include asidewall 114 d having through holes (not shown in FIG. 2) similar to thethrough holes 118 a and the through holes 118 b (shown in FIG. 1). Insome instances, the sidewall 114 d may include additional openings foran additional microphone(s).

In addition to the connector 120, other features can place theelectronic device 100 in communication with external devices. Forexample, the electronic device 100 may include an electrical contact 123a, an electrical contact 123 b, and an electrical contact 123 c. Theelectrical contact 123 a, the electrical contact 123 b, and theelectrical contact 123 c may include metal contacts designed toelectrically couple with an accessory device (not shown in FIG. 2), suchas a cover, a folio, and/or a cover-keyboard accessory.

FIG. 3 illustrates a plan view of the electronic device 100, with thetransparent cover 106 and the display assembly 104 removed to showadditional features. As shown, the enclosure 102 may define an internalvolume 130 that provides a space to carry the components of theelectronic device 100. The electronic device 100 may include a circuitboard 128 that carries several processor circuits (not labeled), some ofwhich may serve as a central processing unit, a graphics processingunit, and a memory circuit, as non-limiting examples. The electronicdevice 100 may further include a battery module 132 a and a batterymodule 132 b that surround (and electrically couple to) the circuitboard 128. The battery module 132 a and the battery module 132 b aredesigned to store and provide energy to the various operationalcomponents of the electronic device 100. Also, the battery module 132 aand the battery module 132 b can be charged using the connector 120.

The electronic device 100 may include a non-metal material 116 c that isengaged (and in some cases, interlocked) with the non-metal material 116b. The non-metal material 116 b (shown as dotted lines) may provide anaesthetic finish to the enclosure 102, while the non-metal material 116c provides a rigid material to add support to the enclosure 102.

The electronic device 100 may include several audio modules in theinternal volume 130 of the enclosure 102. For example, the electronicdevice 100 may include an audio module 134 a and an audio module 136 a.In some embodiments, the audio module 134 a is designed to generateacoustical energy, in the form of audible sound, approximately in therange of 2,000-20,000 Hertz (“Hz”), but in some case the range may behigher than 20,000 Hz. In some embodiments, the audio module 136 a isdesigned to generate acoustical energy, in the form of audible sound,approximately in the range of 20-5,000 Hz. In this regard, the audiomodule 134 a may be referred to as a tweeter, and the audio module 136 amay be referred to as a woofer.

While both the audio module 134 a and the audio module 136 a may besecured (including adhesively secured) with the wall 124, the audiomodule 136 a may secure with internal walls 138 a that extends from thewall 124. The internal walls 138 a may be integrally formed with thewall 124. In other words, the enclosure 102 may be formed from a blockof material that undergoes a machining operation such that the wall 124and the internal walls 138 a are formed as a continuous structure. Asshown in FIG. 3, the internal walls 138 a are positioned between thesidewalls of the enclosure 102. The electronic device 100 may furtherinclude additional audio modules, including an audio module 134 b, anaudio module 134 c, and an audio module 134 d, that include similarfeatures described for the audio module 134 a. Also, the electronicdevice 100 may further include additional audio modules, including anaudio module 136 b, an audio module 136 c, and an audio module 136 d,that include similar features described for the audio module 136 a, withthe audio module 136 b, the audio module 136 c, and the audio module 136d secured with internal walls 138 b, internal walls 138 c, and internalwalls 138 d, respectively.

A partial cross section of the sidewalls of the enclosure 102 showseveral through holes positioned by the audio modules that allowacoustical energy to exit the electronic device 100. For example, thethrough holes 118 a and the through holes 118 b in the sidewall 114 ballow acoustical energy in the audio module 134 c and the audio module134 d, respectively, to exit the electronic device 100. The sidewall 114d includes through holes 118 e and through holes 118 f that serve asimilar function for the audio module 134 a and the audio module 134 b,respectively. The remaining audio modules—the audio module 136 a, theaudio module 136 b, the audio module 136 c, and the audio module 136d—are designed to acoustically drive the wall 124 such that the wall 124resonates and create sound. This will be further shown below. In thisregard, some audio modules may generate acoustical energy by driving airthroughout the internal volume 130, and may not rely upon theaforementioned through holes in the sidewalls. However, it should benoted that some acoustical energy from the audio module 136 a, the audiomodule 136 b, the audio module 136 c, and/or the audio module 136 d mayexit a through hole(s). It should be noted that while a discrete numberof audio modules (eight) are shown, the electronic device 100 mayinclude a different number of audio modules in other embodiments (notshown).

The electronic device 100 may further include several microphones. Forexample, the electronic device 100 may include a microphone 142 asecured with the sidewall 114 c. The electronic device 100 may include aflexible circuit 144 a that carries the microphone 142 a. The flexiblecircuit 144 a may electrically couple to the circuit board 128. Asshown, the flexible circuit 144 a may be routed under the battery module132 a and positioned against the sidewall 114 c.

The electronic device 100 may further include a microphone 142 b and amicrophone 142 c. The sidewall 114 d includes through holes 118 g forthe microphone 142 b and the microphone 142 c to receive acousticalenergy. The electronic device 100 may include a bracket 188 that carriesa vision system (not labeled), as well as the microphone 142 b and themicrophone 142 c. The vision system, and its components, will be furtherdiscussed below. The electronic device 100 may further include aflexible circuit 144 b that electrically couples with the circuit board128, the microphone 142 b, the microphone 142 c, and the components ofthe vision system. The flexible circuit 144 b may also electricallycouple to additional sensors that will be discussed below. Theelectronic device 100 may further include a microphone 142 d. In someembodiments, the microphone 142 d may be integrated with a cameraassembly 126 and the flash module 127.

The electronic device 100 may further include an inductive charging unit148. The inductive charging unit 148 may include a ferrite coil designedto receive an alternating electrical current from at least one of thebattery module 132 a or the battery module 132 b. The direct current(“DC”) provided by the battery module 132 a and/or the battery module132 b may pass through an inverter (not shown in FIG. 3) to generate thealternating electrical current. As a result, the inductive charging unit148 can subsequently provide an alternating electromagnetic field (notshown in FIG. 3) and act as a transmitter coil to inductively charge apower source (not shown in FIG. 3) of an object that is external to theelectronic device 100. Further, the inductive charging unit 148 isaligned with the non-metal material 116 a and the electromagnetic fieldgenerated by the inductive charging unit 148 may pass through thenon-metal material 116 a and induce electrical current into an object(not shown in FIG. 3), such as a digital stylus positioned against thesidewall 114 a. This will be shown below.

The electronic device 100 may include an antenna 152 a and an antenna152 b located along the non-metal material 116 a. The electronic device100 may further include an antenna 152 c located along the non-metalmaterial 116 a and the non-metal material 116 b. The antenna 152 a, theantenna 152 b, and the antenna 152 c may enable wireless communication.Further, each antenna may provide radio frequency communication within aspecific range of frequencies. For instance, the antenna 152 a mayprovide Wi-Fi communication, the antenna 152 b may provide Bluetooth®communication, and the antenna 152 c may provide cellular networkcommunication, each of which are commonly to known to those skilled inthe art to transmit within a given range of frequencies. It should benoted other combinations of wireless communication are possible, and thelocation of the antenna 152 a, the antenna, and the antenna 152 c may beinterchanged.

The electronic device 100 may further include several magnetic elementspositioned in the internal volume 130. The magnetics elements may referto permanent magnets or other magnetically attractable materials. Themagnetic elements shown and described in FIG. 3 may refer to a group orset of magnetic elements, or may include an individual magnetic element.

The electronic device 100 may include magnetic elements 154 a andmagnetic elements 154 b positioned along the sidewall 114 c. Themagnetic elements 154 a and magnetic elements 154 b are designed tomagnetically couple with magnetic elements in an accessory device (notshown in FIG. 3), such as a cover, a folio, or a cover-keyboardaccessory. Further, the magnetic elements 154 a and magnetic elements154 b may position the electronic device 100 in a manner such that thesidewall 114 c defines a base for the electronic device 100.

The electronic device 100 may include magnetic elements 154 c andmagnetic elements 154 c positioned along the wall 124. The magneticelements 154 c and magnetic elements 154 d are designed to support theelectrical contact 123 a and the electrical contact 123 b. For example,when the electronic device 100 is coupled to an accessory device (notshown in FIG. 3) with electrical contacts that engage the electricalcontact 123 a, the electrical contact 123 b, and the electrical contact123 c, the magnetic elements 154 c and magnetic elements 154 d may applya repulsive magnetic force to magnetic elements in the accessory device.The repulsive magnetic force may repel the accessory device in a mannerthat reduces the amount of force or pressure applied to the electricalcontact 123 a, the electrical contact 123 b, and the electrical contact123 c.

The electronic device 100 may include magnetic elements 154 e andmagnetic elements 154 f positioned along the sidewall 114 a, and inparticular, along the non-metal material 116 a. The magnetic elements154 e and magnetic elements 154 f are designed to magnetically couplewith magnets in the object that can be positioned against the sidewall114 a and inductively charged by the inductive charging unit 148. Forexample, a digital stylus (not shown in FIG. 3) may include magnets thatmagnetically couple with the magnetic elements 154 e and magneticelements 154 f such that the digital stylus is retained by theelectronic device 100 during an inductive charging event. Also, themagnetic elements 154 e and magnetic elements 154 f can be used togenerally store the digital stylus against the sidewall 114 a.

The electronic device 100 may further include magnetic elements 154 gdesigned to magnetically couple with magnets of an accessory device (notshown in FIG. 3) designed to cover the electronic device 100. Theelectronic device 100 may further include several magnetic elementspositioned within some of the audio modules. For example, the electronicdevice 100 may include magnetic elements (not labeled, shown as dottedlines) covered by the audio module 136 a, the audio module 136 b, theaudio module 136 c, and the audio module 136 d. The magnetic elementscovered by the aforementioned audio modules located along the wall 124and between their respective internal walls are designed to magneticallycouple with magnets in an accessory device (not shown in FIG. 3) inorder to hold the accessory device against the wall 124. Also, the audiomodule 136 a, the audio module 136 b, the audio module 136 c, and theaudio module 136 d may include integrated magnets (including a permanentmagnet) separate from the aforementioned magnetic elements that areshown as dotted lines. The magnets that are integrated with the audiomodules are used to produce acoustical energy. In order to promoteinstallation of the audio module 136 a, the audio module 136 b, theaudio module 136 c, and the audio module 136 d with their respectiveinternal walls, the magnets of the audio module 136 a, the audio module136 b, the audio module 136 c, and the audio module 136 d may include anopposing magnetic polarity as that of the magnetic elements (shown asdotted lines). This may provide a magnetic attraction force and/or limitor prevent a magnetic repulsion force.

FIG. 4 illustrates a plan view of the transparent cover 106 and thedisplay assembly 104, further showing several circuits used inconjunction with the display assembly 104. The display assembly 104 mayinclude a flexible circuit 156 a extending from one end of the displayassembly 104, and a flexible circuit 156 b extending from another(opposing) end of the display assembly 104. In particular, the flexiblecircuit 156 a and the flexible circuit 156 b may extend from opposingends of a touch input layer (not shown in FIG. 4) of the displayassembly 104. The flexible circuit 156 a and the flexible circuit 156 bmay wrap around and electrically connect to the circuit board 128 (shownin FIG. 3). Also, a circuit board 158 (shown as a dotted line) maycouple with the display assembly 104. The circuit board 158 may includea timing controller board designed to drive the display assembly 104.The circuit board 158 may include a flexible circuit 162 a and aflexible circuit 162 b (shown as dotted lines), both which electricallyconnect to the circuit board 128 (shown in FIG. 3).

The display assembly 104, or a metal chassis (not shown in FIG. 4) thatis coupled to the display assembly 104, may carry additional structuresand components. For example, a magnetic element 154 h and a magneticelement 154 i may couple with the display assembly 104 (or theaforementioned metal chassis). The magnetic element 154 h and themagnetic element 154 i may magnetically couple with an accessory device(not shown in FIG. 4) designed to overlay and protect the transparentcover 106 and the display assembly 104. Also, a microphone 142 e maycouple with the display assembly 104. The microphone 142 e may utilizethe through holes 118 a (shown in FIG. 3) to receive acoustical energy.

FIG. 5 illustrates a side view of the transparent cover 106 and thedisplay assembly 104 shown in FIG. 4. As shown, the display assembly 104may include a touch input layer 104 a coupled to the transparent cover106. The display assembly 104 may further include a display layer 104 bcoupled to the touch input layer 104 a. The coupling means may includeadhesives (not shown in FIG. 5). The flexible circuit 156 a may extendfrom the touch input layer 104 a and wrap around the display layer 104 bto electrically connect to the circuit board 128 (shown in FIG. 3). Theflexible circuit 162 a and the flexible circuit 162 b (not shown in FIG.5) may extend from the display layer 104 b to electrically connect tothe circuit board 128 (shown in FIG. 3).

FIG. 6 illustrates a cross sectional view of the electronic device 100,showing various electrical connections between the display assembly 104and the circuit board 128. As shown, the flexible circuit 156 a and theflexible circuit 156 b wrap around and pass over the battery module 132a and the battery module 132 b, respectively, and electrically andmechanically couple to the circuit board 128 to place the touch inputlayer 104 a in communication with the circuit board 128 as well as anyprocessor circuits (not shown in FIG. 6) coupled to the circuit board128. Also, the flexible circuit 162 a and the flexible circuit 162 b(both shown as dotted lines, as they are out of plane) electrically andmechanically couple to the circuit board 128 to place the display layer104 b and the circuit board 158 (shown in FIG. 4) in communication withthe circuit board 128 as well as any processor circuits (not shown inFIG. 6) coupled to the circuit board 128. As shown in the enlarged view,the border 108 may cover the edges of the display assembly 104, as wellas electrical connections to the touch input layer 104 a and the displaylayer 104 b. As a result, the display layer 104 b of the displayassembly 104 may illuminate and present visual information, which may beviewable except for at the border 108, and the electrical connects areobscured by the border 108. Also, in order to protect the displayassembly 104, a chassis 164 can couple with the display assembly 104.The chassis 164 may include a metal chassis.

FIG. 7 illustrates a plan view of the electronic device 100, showingseveral audio modules positioned in the enclosure 102. As shown, theaudio module 136 a may include a cover 168 a that connects to theinternal walls 138 a. The cover 168 a may include a metal, such asstainless steel (including SUS stainless steel). However, other metalsand non-metals (such as carbon fiber) are possible. When the audiomodule 136 a generates acoustical energy, the audio module 136 a causesacoustical vibration of the wall 124 and drives air throughout theinternal volume 130. Further, the cover 168 a may include a raisedportion 172 a that can direct at least some of the driven air around theaudio module 134 a and in a direction toward the through holes 118 e,shown by a partial cross section of the enclosure 102. Similarly, theaudio module 136 c may include a cover 168 c that connects to theinternal walls 138 a. When the audio module 136 c generates acousticalenergy, the audio module 136 c causes acoustical vibration of the wall124 and drives air throughout the internal volume 130. Further, thecover 168 c may include a raised portion 172 c that can direct at leastsome of the driven air around audio module 134 c and in a directiontoward the through holes 118 a, shown by a partial cross section of theenclosure 102. Additional audio modules (including the audio module 136b and the audio module 136 d, shown in FIG. 3) may include features andproperties similar to those described for the audio module 136 a and theaudio module 136 c.

FIG. 8A illustrates a plan view of the back of the electronic device100, showing the non-metal material 116 b and multiple linked sectionsof the enclosure 102 covered by the non-metal material 116 b. Whenopenings in the wall 124 are formed, the removed material from theenclosure 102 reduces the overall rigidity of the enclosure 102.However, during a material removal operation to form openings in thewall 124, a cutting tool (not shown) can be controlled such that alinked section 174 a, a linked section 174 b, and a linked section 174 cremain after the material removal operation. The aforementioned linkedsections act as bridges to retain at least some structural integrity ofthe enclosure 102 subsequent to a material removal operation. As aresult, the enclosure 102 is less likely to warp or bend.

FIG. 8B illustrates an alternate embodiment of an electronic device 200,showing a non-metal material 216 b that extends to the edges of anenclosure 202 of the electronic device 200, in accordance with somedescribed embodiments. The electronic device 200 may include anyfeatures described herein for an electronic device, such as theelectronic device 100 (shown in FIG. 1). A material removal operationmay extend not only along a wall 224, but also to sidewalls (not shownin FIG. 8B) that are similar to the sidewall 114 a and the sidewall 114b (shown in FIG. 1), as well as the sidewall 114 d (shown in FIG. 3).The additional removed material may permit additional area for antennaeand accordingly, additional area for radio frequency transmissionthrough the enclosure 202 when, for example, the electronic device 200includes a cellular network antenna and associated processing circuitry(not shown in FIG. 8B). However, the material removal operation to formthe opening in the wall 224 can be controlled such that a linked section274 a, a linked section 274 b, and a linked section 274 c remain afterthe material removal operation.

FIG. 9 illustrates a cross sectional view of the electronic device 100,showing the audio module 136 a generating acoustical energy. As shown,the cover 168 a of the audio module 136 a is adhesively secured to theinternal walls 138 a. The audio module 136 a may include a magneticelement 176 a coupled to the cover 168 a. As shown, the raised portion172 a of the cover 168 a creates a corresponding recessed portion. Thecorresponding recessed portion may be formed though an embossingoperation to the cover 168 a. Also, the corresponding recessed portioncreates a path that can be used to direct air driven during use of theaudio module 136 a. Also, during use of the audio module 136 a, thecover 168 a may move relative to the internal walls 138 a. However, theraised portion 172 a may contact the chassis 164 and provide a bufferfor the audio module 136 a to prevent unwanted sound generation throughcontact with the chassis 164. Also, the audio module 136 a may include aprotective material 173, which may include compressible foam thatfurther prevents unwanted sound generation through contact with thechassis 164. Also, the cover 168 a may include an opening 175 (ormultiple openings) that provides a vent that relieves air pressurewithin the space defined by the cover 168 a and the internal walls 138a.

The audio module 136 a may further include a magnetic element 176 badhesively secured to the wall 124. In some embodiments, the magneticelement 176 a is a permanent magnet and the magnetic element 176 b is anelectromagnet that includes a coil designed to receive an alternatingelectrical current that causes an alternating magnetic polarity. Thealternating magnetic polarity causes a magnetic attraction and magneticrepulsion between the magnetic element 176 a and the magnetic element176 b, causing relative movement of the magnetic element 176 b withrespect to the magnetic element 176 a. The relative movement may occurat a frequency in accordance with the frequency of the alternatingcurrent provided to the magnetic element 176 b.

Due in part to the coupling between the magnetic element 176 b and thewall 124, the wall 124 may move in conjunction with the movement of themagnetic element 176 b. For example, the wall 124 may move toward andaway from the magnetic element 176 a accordance with the frequency ofthe alternating current provided to the magnetic element 176 b, therebycausing the wall 124 to resonate and produce acoustical energy 178 inthe form of audible sound. In other words, the wall 124 is acousticallydriven by the audio module 136 a. The remaining audio modules (such asthe audio module 136 b, the audio module 136 c, and the audio module 136d) may operate in a similar manner.

When the display assembly 104 is assembled with the enclosure 102, theantenna 152 c (shown in FIG. 3) may be sensitive to the chassis 164, asthe chassis 164 may include metal and, as a result, may carry someelectrostatic charge if not electrically grounded. In order to eliminatethis issue, the chassis 164 may be electrically grounded. For example,an electrically conductive layer 182 may couple to the chassis 164 andthe enclosure 102, including a ledge 184 of the enclosure 102 thatreceives the transparent cover 106. The electrically conductive layer182 may include a copper adhesive, such as copper tape. Othermetal-adhesive combinations are possible. In some instances, theelectrically conductive layer 182 is secured to the ledge 184 by anelectrically conductive adhesive (not shown in FIG. 9). Also, theelectrically conductive layer 182 may adhesively secure to thetransparent cover 106 and/or the border 108 by an adhesive (not shown inFIG. 9). Further, as shown in the enlarged view, a film 186, at leastpartially surrounded by the electrically conductive layer 182, mayadhesively secure with the electrically conductive layer 182. In someembodiments, the film 186 is a heat-activated film designed to provideadhesive properties when heat and/or pressure is/are applied (to thefilm 186) by, for example, an assembly operation between the transparentcover 106 and the enclosure 102. The film 186 may include somecompressive properties, which promotes positioning the transparent cover106 along the Z-axis in a consistent and repeatable manner duringassembly. The compressive properties may compensate for structuralvariances and tolerances in the components.

The electronic device 100 may further include magnetic elements 154 mpositioned between the internal walls 138 a. Despite the proximity tothe magnetic element 176 a and the magnetic element 176 b, the magneticelements 154 m may not interfere with the audio module 136 a, and maycouple with magnetic elements embedded in an accessory device (not shownin FIG. 9).

FIG. 10 illustrates an enlarged plan view of the electronic device 100,showing the vision system 190 as well as additional components. Thetransparent cover 106 and the display assembly 104 are removed to showthe components. As shown, a bracket 188, which may include one or morebracket parts, carries the vision system 190. The bracket 188 may besecured (either adhesively and/or fastened) with the wall 124. Thevision system 190 may electrically couple with the flexible circuit 144b, which is electrically coupled to the circuit board 128 (shown in FIG.3).

The vision system 190 may include several components used for objectrecognition, including facial recognition. For example, the visionsystem 190 may include a camera module 192 a designed to capture animage of an object. The vision system 190 may further include a firstlight-emitting module 192 b designed to project a light pattern,including a pattern of laser light dots, onto the object. The firstlight-emitting module 192 b may emit infrared (“IR”) light. The visionsystem 190 may further include a light-receiving module 192 c designedto receive at least some of the light pattern (generated by the firstlight-emitting module 192 b) that is reflected from the object. Toprovide additional light when ambient light is relatively, the visionsystem 190 may further include a second light-emitting module 192 d,which may also emit IR light. For purposes of safety, a filter (notshown in FIG. 10) may cover the second light-emitting module 192 d. Thecomponents of the vision system 190 are positioned between the sidewall114 d and an imaginary line 195 (represented by a dotted line), whichrepresents a position of the border 108 (shown in FIG. 1).

When used for facial recognition, the vision system 190 may be used toauthenticate a user by comparing a prior saved (reflected) dot patternof the user's face with a current (reflected) dot pattern of the user'sface. A facial recognition software application (not shown in FIG. 10)may compare and authenticate if the current dot pattern is at or above apredetermined percent match with the saved dot pattern. When the user isauthenticated using the facial recognition software application, theelectronic device 100 may unlock and grant access to the user.

The bracket 188 may carry additional components. For example, thebracket 188 may carry the microphone 142 b and the microphone 142 c. Insome instances, the microphone 142 b and the microphone 142 c aresensitive to light energy from one or more of the light-emitting modulesof the vision system 190. In this manner, a light-blocking tape 196 aand a light-blocking tape 196 b may cover and shield the microphone 142b and the microphone 142 c, respectively, from the light from the one ormore light-emitting modules of the vision system 190. The bracket 188may carry sensors, such as a sensor 194 a and a sensor 194 b. In someembodiments, the sensor 194 a is a proximity sensor and the sensor 194 bis an ambient light sensor. The vision system 190 may rely upon thesensor 194 b to determine, based upon light intensity measured from thesensor 194 b, when to activate the second light-emitting module 192 d.

FIG. 11 illustrates a cross sectional view of the electronic device 100,showing the vision system 190 and the components shown in FIG. 10, andfurther showing the border 108 having openings with a material fillingthe openings of the border 108. As shown, the border 108 is secured tothe transparent cover 106. The border 108 may include an opaquematerial, such as an opaque ink or paint. Also, the border 108 generallycovers the vision system 190. In order for the vision system 190 toperform object recognition, the border 108 includes openings, or voids,to permit light transmission through the border 108. For example, theborder 108 may include an opening with a material 198. The material 198may include a translucent material, or a light transmitting material,such as translucent ink. Further, the material 198 may match, or may besubstantially similar to, the appearance of the border 108 in terms ofcolor and/or reflectivity. For example, when the border 108 is black,the material 198 appears black. Other appearances (e.g., color,reflectivity) are possible. This allows the border 108 to appear atleast partially continuous, while the material 198 at least partiallyobscure the components of the vision system 190. The material 198permits light to reach the camera module 192 a and the light-receivingmodule 192 c, and permits light from the first light-emitting module 192b and the second light-emitting module 192 d to pass such that lightexits the electronic device 100. The material 198 further permits lightto reach the sensor 194 b and the sensor 194 a (not shown in FIG. 11).

FIG. 12 illustrates a plan view of the electronic device 100, showing anobject 302 positioned against the sidewall 114 a. The object 302 mayinclude a digital stylus capable of interacting and providing an inputto the display assembly 104, and in particular, the touch input layer(not shown in FIG. 12) of the display assembly 104. In order for theobject 302 to function and change the electrostatic field of the touchinput layer, the object 302 requires a battery 304 to supply electricalcurrent to a capacitive component and to radio frequency components (notshown in FIG. 12) of the object 302, both of which may be used tocommunicate with the electronic device 100. The battery 304 of theobject 302 may include a rechargeable battery.

The inductive charging unit 148 of the electronic device 100 is designedto charge the battery 304 of the object 302. The inductive charging unit148 may act as transmitter coil and inductively charge the battery 304by inducing an alternating current (“AC”) to a receiver coil 348 of theobject 302. The induced current may pass through an AC-to-DC converter,such as a rectifier, and may subsequently be used to charge or rechargethe battery 304. To induce the current to the battery 304, the inductivecharging unit 148 and the object 302 are positioned along the non-metalmaterial 116 a. An additional non-metal material 116 d may be present toprovide additional rigidity along the sidewall 114 a. The additionalnon-metal material 116 d may include a resin and/or a hardened adhesive.In order to maintain the object 302 against the sidewall 114 a (oragainst the non-metal material 116 a), the magnetic elements 154 e andthe magnetic elements 154 f may magnetically couple with magneticelements 354 a and magnetic elements 354 b, respectively, in the object302. Also, as shown, the antenna 152 a and the antenna 152 b arepositioned along the non-metal material 116 a and the additionalnon-metal material 116 d, thereby allowing the antenna 152 a and theantenna 152 b to send and receive RF communication.

FIG. 13 illustrates a partial view of the electronic device 100, showingthe connector 120 and connector retaining elements along the connector120. As shown in the enlarged view, the connector 120 may include aretainer element 121 a and a retainer element 121 b. The retainerelement 121 a and the retainer element 121 b are designed to engage andretain an external connector (not shown in FIG. 13) of a cable assembly,thereby allowing the electronic device 100 to send and receive data, aswell as receive electrical current to charge the battery modules (notshown in FIG. 13). The retainer element 121 a and the retainer element121 b are further designed to protect and shield the connector 120. Forexample, the retainer element 121 a and the retainer element 121 b aredesigned prevent excessive contact with the connector 120 as a result ofcycling (connecting and disconnecting) between the connector 120 and theexternal connector. This may prevent the connector 120 from unwantedwearing. The retainer element 121 a and the retainer element 121 b maybe formed through injection molding, including metal injection molding.As a result, the retainer element 121 a and the retainer element 121 bmay include metal. Also, the retainer element 121 a and the retainerelement 121 b may be applied to the connector 120 by soldering.

FIG. 14 illustrates a cross sectional view of the electronic device 100,showing the microphone 142 a positioned along the enclosure 102. Asshown, the microphone 142 a is electrically and mechanically coupled tothe flexible circuit 144 a. The flexible circuit 144 a may run along thewall 124 and the sidewall 114 c such that the microphone 142 a isaligned with an opening (not labeled in FIG. 14) of the sidewall 114 c.The flexible circuit 144 a may adhesively secure with the wall 124 andthe sidewall 114 c. Also, the flexible circuit 144 a runs below thebattery module 132 a such that the flexible circuit 144 a is positionedbetween the battery module 132 a and the wall 124.

FIG. 15 illustrates a side view of the electronic device 100 carried byan accessory device 400, in accordance with some described embodiments.The accessory device 400 may include a folio or a cover. The accessorydevice 400 may include a first cover portion 402 a coupled with a secondcover portion 402 b by a hinge 404. The first cover portion 402 a maycover the transparent cover 106 and the display assembly 104 (not shownin FIG. 15). In order to retain the first cover portion 402 a with theelectronic device 100, the first cover portion 402 a may includemagnetic elements 454 a and magnetic elements 454 b that magneticallycouple with the magnetic element 154 h and the magnetic element 154 i,respectively, with the magnetic element 154 h and the magnetic element154 i secured with the display assembly 104 (as shown in FIG. 4).

The second cover portion 402 b may include a keyboard (not shown in FIG.15) designed to interact with the electronic device 100. In order toretain the second cover portion 402 b with the electronic device 100,the second cover portion 402 b may include magnetic elements 454 c,magnetic elements 454 d, and magnetic elements 454 e. The magneticelements 454 c may magnetically couple with magnetic elements 154 j inthe electronic device 100. The magnetic elements 454 d and the magneticelements 454 e may magnetically couple with magnetic elements 154 k andmagnetic elements 154 l, respectively, in the electronic device 100. Themagnetic elements 154 k and magnetic elements 154 l may representmagnetic elements located on the wall 124 between the internal walls ofan audio module (shown in FIG. 3). For example, the magnetic elements154 k and magnetic elements 154 l may be located between the internalwalls 138 d and the internal walls 138 b (shown in FIG. 3),respectively.

The magnetic elements in the electronic device 100 may be relativelysmall in size. This may promote aligning (e.g., centering) theelectronic device 100 with respect to the accessory device 400. Whereasfewer, larger magnetic elements in the electronic device 100 may providea stronger magnetic coupling force with magnets of the accessory device400, the smaller magnetic elements may ease a user's ability to alignthe electronic device 100 with the accessory device 400. Further, therelatively large number of small magnets may at least partiallycompensate for a relatively large external magnetic field generated by asingle, relatively larger magnetic element. As a result, the magneticelements of the electronic device 100 remain magnetically coupled withthe magnetic elements of the accessory device 400.
